Correlation of Ultrastructure with Mechanical Properties of Nano‐Hybrid Dental Composites

Determination of mechanical properties of nano-hybrid dental composites leads to strong correlation to material's ultrastructure. Not only does total filler content in percentage of weight affect the mechanical properties, but the combination of optimal filler size and shape with homogeneous distribution of filler particles and an optimal amount of different sized fillers in finally cured dental composites lead to desired mechanical and thermo-mechanical properties.
